v This invention relates to anew and improved printing-press for general use, but more especially designed for printing labels or small bills, Ste.

'Ihe object for the invention is to obtain a press of silnple construction by which any per' son cando their own printing in a small waydruggists, for instance, print their own labels, storekeepers their own circulars, bill-heads, Src.

The invention will prove valuable in those cases where dates are pnt on labels, and consequently require to be changed every day, and where the titles on labels are frequently changed.

The invention consists in the employment or use of a type-cylinder ari au ged with a pressure-cylinder andan inking device, as hereinafter fully shown and described.

Arepresents the framing of the press, which may be constructed in any suitable manner to support theworking parts. Two side pieces, a a, attached to a base, b, will answer for a framing. The inking device is composed of three rollers, B B B, all of which are shown in Fig. 3. The rollers B and B may be made of wood or iron; The roller B may be ofl wood covered with felt, or a roller of glue and molasses may be used.

The roller B has its journals fitted in adjust-able bearings, which may be operated or (See Fig. 3.) ,A Other means, however, may be employed for this purpose, so as to graduate the pressure of roller B against roller B and the hereinafter described.

type-roller C,

` The upper roller, B, besides a rota-ry motion, has a longitudinal vibrating motion given 1t. The means shown in. the drawings for ei'- tectin g this result are composed ot' two cams, l)

D, one at each end of the roller, and placedin opposite positions, said cams coming alternately in contact with pins b', iitted permanently in the bearings c, in which the cams work or rotate. Various plans, however, may

be devised for this purpose. Y

The type cylinder Chas its shaft E working in xed bearings. This cylinder, in cases where the type or form requires to be changed p oral tered for dates, Src., is constructed as follows:

On the shaft E there are placed two circular metal heads, F and F', one of which, F, `has a circular recess, d, made in its inner side, to receive a circular wooden head, c, to whichlongitudinal wooden segments, j',\are attached at one end by nails or screws g. (See Fig. 2.) 'lhe opposite ends ot' the segments f are also attached by nails or screws, g'. to a similar head, e. The metal heads F F are clamped firmly onthe shaft E by nuts G G, as shown in Fig. 2. Between the wooden segments j' the types h are placed, which require to be frequently changed, as types for dates, for in-` stance, the segments f being made of such di mensions as to admit of that arrangement. These types hare securedin position by screws i, which pass through the metal head F and bear against types or quads, as shown in-Fig. 2. VTo the exterior ot' segments f stereotype`- plates j are tacked or screwed, said plates j being that portion of the form which does not require to be frequently changed.

In cases where permanent forms are to be used the type-cylinder may be composed entirely ofwood, with stereotypcplates attached to its periphery.

II represents a cylinder, against which the type-cylinder bears, and between which and the type-cylinder the paper to be printed upon passes. This cylinder H may be of wood or iron covered with india-rubber,` and paper placed over the latter in order to obtain the necessary yielding property and at the same time have a certain degree of lirlnness to insure a clean impression being taken. ltubber alone would be too yielding, `a-nd the impression blurred by the sinkingof the type into it.

From the above description it will be seen that by turning the type-cylinder C the latter will have its type or form perfectly inked through the medium of the inkin g device composed of the rollersB B B and by passing the paperbetween the type-cylinderO and cylinder Il the paper Will be printed or receive the impression from the type or form on cylinder C, the pressure ofthe type`or form on the paper being graduated by adjustingl the bearings of the cylinder H, the latter being adjusted by means of set-screws ai, weights, or any other suitable means.

Thus by this simple arrangement a very efcient printing-press is obtained, one that may be operated by any one of ordinary ability. It will answer au excellent purpose for retail HENRY REDLIC ll.
